The Narada attacked Vulcan, destroying all of the Starfleet ships that attempted to intervene. Though the Enterprise crew tried to foil this plan, the Narada successfully drilled into the core of the planet and placed Red matter there, creating an artificial black hole at the core, which promptly consumed the planet.

The Narada then attempted to destroy Earth in a similar manner, but through the actions of Captain Kirk and Spock, an artificial black hole was created which then consumed the Narada. (TOSmovie: Star Trek)

After stopping at the Aldebaran colony, the Enterprise prepared to leave the Milky Way galaxy when it intercepted a record-marker from the SS Valiant. Spock was able to analyze the memory banks, revealing an unknown force in the region that forced her captain to destroy his own ship.

Continuing its course to our galaxy's boundary, the Enterprise encountered an unusual force field known as the galactic barrier. Nine crewmembers died, and another was injured—Kirk's friend, Lieutenant Mitchell. The Enterprise also lost her warp capability.

Under the care of Leonard McCoy, Mitchell began to exhibit unusual powers, such as levitation and telepathy. At a senior staff meeting in the briefing room, the crew agreed to maroon Lieutenant Mitchell on "another Delta Vega."

Arriving at Delta Vega I, Kirk and McCoy prepared Mitchell for exile when he attacked Kirk with a blast of energy from his hands. McCoy made a split decision to knock him out with a sedative. He was later beamed down to the planet, with Kirk and Spock, while Scott and Kelso searched the facility for materials they needed to restore the ship's warp drive.

Mitchell revived, escaped his force field, then stunned Kirk and Spock with the energy from his hands. He later met Kelso, and forced his former friend to shoot and kill himself with his phaser.

Scott revived Kirk and Spock, telling them Mitchell had escaped and Kelso was dead. Kirk made a command decision to confront Mitchell, ordering Spock to quarantine the planet and leave if he had not returned in three hours.

Awaiting him in the desert, Mitchell demonstrated his power of illusion to Kirk by transforming the landscape around them into the bar from Iowa. Returning the landscape to its original state, Mitchell forced Kirk to kneel before him and beg forgiveness for his failure and his humanity. As he did so, Spock came up behind Mitchell and nerve-pinched him. Kirk ordered Spock to stand back, then shot and killed his friend.

Kelso and Mitchell were buried in space. Spock later joined Kirk in the briefing room, offering to play chess with him. Kirk accepted the offer, and Spock left for Engineering, leaving him alone in the briefing room.

An escape pod was found and its occupant, Kalara, informed the Yorktown crew that her ship was stranded on Altamid. CommodoreParis agreed to let Kirk and the Enterprise enter the Necro Cloud to assist her. However, once in orbit around Altamid, the Enterprise came under attack by a swarm of ships. The Enterprise tried to escape but was crippled and boarded by Swarm drones led by warlord Krall and Manas. Kirk and his crew were then forced to abandon ship before it's saucer section crash-landed on Altamid. However, most of the crew had been captured save for Kirk, Chekov, Spock, Kalara, McCoy and Scotty.

With the assistance of fellow crash victim Jaylah, the still-free members of the senior staff were able to reunite at her "house", the wreck of the NX-class variant USS Franklin. After rescuing the prisoners in a raid on Krall's base, they repaired USS Franklin and pursued Krall's swarm to Yorktown Station, where they were able to destroy the swarm by using a radio transmission of the Beastie Boys' song "Sabotage" to jam its communications. They then pursued Krall into the station and were able to foil his attempt to deploy a biological weapon against its inhabitants.

Kirk and his crew on the Endeavour encountered the Borg, who had followed traces of Borg technology from the Narada to the Alpha Quadrant. Kirk tracked the lonely sphere back to Romulus, where the combined forces of the Endeavour and the Romulans were able to destroy it. (TOS - Boldly Gocomics: "Issue 1", "Issue 2", "Issue 3", "Issue 4")
